Mercedes are hoping that they will be allowed to get one day of running at the Young Driver Test, according to a report.
The Brackley squad were found guilty of breaking the regulations and bringing the sport into disrepute after they conducted a three-day "private tyre test" with Pirelli in Spain.
The International Tribunal's decision to ban the team from running at the Young Driver Test was widely regarded as lenient, but things have changed since the FIA announced that race drivers will be allowed to trial Pirelli tyres at the test in the wake of the British GP blowouts.
Autosport claims Mercedes are now hoping to take part in the Silverstone test and are 'awaiting a ruling from the FIA on whether or not there are grounds for it to get some running, so it can gather some data about the new tyres ahead of the Hungarian Grand Prix'.
Mercedes motorsport boss Toto Wolff told Autosport it was "a work in progress" and that safety was an issue.
"When it is about safety it would be good if all teams are clear whether they [the tyres] work on their cars," he said. "But it is up to the FIA to decide.
"Safety is the priority for the FIA and I am sure they would safeguard that it is the same for everybody."
The Silverstone test will take place from July 17-19 and Mercedes team principal Ross Brawn concedes they are unlikely to be allowed to test over the three days.
"If it was extended to a fourth day then we would have an argument that the fourth day - an extra day - should be made available to us as our penalty was three days," Brawn said.
"I haven't heard the latest on what [other teams] are doing with drivers as it seems to vary.
"We certainly won't be able to attend the three days and it doesn't look like it is going to be extended."
